MONTJ'MENTAL DAG-UERREOTYPE-CASES.

Speccaton of Letters Patent No. 22,850, dated February 8, 1859.

To all whom it may concern:

Be it known that I, JACOB Bnnesfrnnssnn, of Berrysburg, in the county ofDauphin and State of Pennsylvania, have invented a new and usefulImprovement in Glass Menu mental Daguerreotype-Cases; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming apart of this specication, in which- Figure l, is a front view of a glassmonumental daguerreotype case, exhibiting my invention. Fig. 2, is atransverse section of the same.

Similar letters of reference in each of the figures indicatecorresponding parts.

The nature of my invention consists in the combination of the centralframe incased by a central raised bead on the rear side of a glass platewith the outer frame incased by an outer raised bead. The central frameand outer frame being cast together on the same glass plate and theouter one being deeper than the inner or central frame.

vBy this invention, a frame is provided at the center of the glass platefor the reception of a miniature or daguerreotype and a frame for thereception of lettering, foliage or any other devices outside of thepicture frame. The picture and devices are kept perfectly air tight asthe inner frame receives cement which prevents the insinuation of air,and the outer frame also receives plaster or other substance whichcompletely incloses and .surrounds the inner frame and also excludes airfrom the outer frame.

The raised beads on the back of the glass plate present at a distance,the appearance of raised ornaments formed on the front of the plate andthus the miniature and devices are separated and each is thrown in thebach ground, and the front of the glass plate has a pleasing reliefgiven to it. The necessity of having ornaments which would interferewith the molding of the case, in order to relieve the appearance of thesame.

It is very essential to use glass frames as they are cheaper than iron,they are also more durable than iron ones, and retain theirneatappearance longer; as glass, unlike iron, is not liable to corrodeby contact of moisture therewith.

In the drawings I have represented a daguerreotype case of oneornamental configuration, but it must be evident that various styles andshapes may be adopted.

A, represents the mounmental daguerreotype or miniature case, it is madeof glass with a rim a, projecting from its rear side as shown in Fig. 2,so that it shall have strength and may be easily embedded' and firmlyset in the cement or other material which is used for confining it inplace, on the monument. It also has a bead projecting in relief from thecentral portion of its rear side as shown in Fig. 2. This b-ead inclosesthe space which receives the daguerreotype or miniature, and is deepenough to receive and contain the same, and also a deep bed of cement C,for confining it in place and eX- cluding air or moisture from it. Bythus forming a bead on the rear side of the case the miniature appearsat a distance as though it were surrounded by an ornament formed on thefront 0f the face of the case, and thus the miniature has the appearanceof being thrown in the back ground and the case has anv ornamentalrelieved appearance notwithstanding its surface is plain.

That I claim as my invention and desire to secure byiLetters Patent, is-

The combination of the central frame incased by a central raised bead onthe rear side of a glass plate with the outer frame incased by an outerraised bead a, the central fra-me and outer frame being cast together onthe same glass plate and the outer one being deeper than the inner orcentral frame substantially as and for the purposes set forth.
